Be it known that L'JOHN Len, a citizenof the United States of America, and .a resident of Stuart,l Adairv county, Iowa, have invented certain ,new and useful Improvements in Devices forRegulating the lVater- Level in Boilers, of which the `following is a specification.

My invention relates to improvements in devices for regulating the `Water-level of4 boilers, and the object kof my improvement is to provide intermediate ,iinechanism A,between a steam boiler and i'tsiinjector, ,op-

erated by pressure ,of Water Vor steam -re`` ceived from the boiler yto either -,close.oiopen the steam and Water valves of the injector to regulate the Water level `in the` boiler. This object have .accomplishedby the4 meansr which are hereinafter described and claimed, and ,which .areillustrated` in the accompanying drawmgs, in which: theft@- ure is a vertical longitudinalsection oaf my improved .device for regulating the @vater level in boilers, with parts `olii the communications theretobroken away. p

The numeralZG denotes a jshort cylinder containing a reciprocatory piston 27, Whose pistonfrod 28 projects externally .tlrensual' manner, and has lits outer end connected atr to an arm 31. Connecting-,rods and SG pivoted at 33 `and Se, respectively, to the eX- tremities of the arm 31, connect ysaid arm to the steam-valveand the Water-valve of an injector adapted tosupply Water to, a steamboilcr said injector 'and boiler I.not shown). The numerals 29' and .30 denote drain-.cocks placed in the bottom .ofa 4cylinder 26 at opposite ends thereof, and adapted Yto drain the water of condensa-tion from `the same on` opposite sides of the Apiston 27. `The numerals 1l and 15' denote pipes leading from opposite heads ofl said ,cylinder tojconvey steam into opposite ends `of said cylinder;y

The ninneral 1 denoteswa vessel or other hollow chambenivith open top tclosedbv a disk-shaped `cover d ,detachably secured thereon .by screws.` cover 4L has a de- )endino inteoral )art s aaced therefrom and v h b 5 having a central vertical threaded opening in said cover, the opening being A,adapted to receive the threaded upper `end of the l1ollow depending structure or tube 6, Whose lower end is somewhat widened in diameter and made convex downward-ly. .Ar steampipe 7 is extended down through the open-` ing in said cover fl and centrally through the tube G in spaced relation .thereto to; eX?

tend a distance'below the loiver end ofsaid` tube. The projecting` end of the said pipe I6 above the cover d is in communication with the upper `part of the boiler or the steamdome thereof. y

The chamber 1 has an overlioiv pipe 22 inserted in its cover 1, and into thesmall inclosed chamber 37 thereof which opens into the tube 6. `Said chamber 1 also has at lits .upper end a pipe 2a inserted :in its side Wall 1n communication with the Water ,in said` boiler. The pipe 24 and the .chamber 1 are suitably located with relation to the boiler` so that the wat-erelevel in the latterwvill vbe just above 'the pipe 2li, While, the pipe, 241; will be but a littlebelowthe level ofthe/.top ofy the float 2., Said chamber 1 has a central hollow stein 3, `closed at its ,lower A,e1-,1d

vbut provided ,with a drain pipe 2O.Y f.

tends into .the hollow of .the chamber land haspits L,topconcavedto tit theconvexjlotver end of the ytube 6, and alinedk therewith. The numeral 2 denotes fafrelatively largey open-top cup-shaped ybody .oriloan integral andrconcentric vwith the upper ,part ofthe valve-body 8. kThe "lower partei Vthesteamf pipe 7 extends down-centrally into the `diminished stem 8, and is closed bv cap ,38... The body 8 has a central 4bore alined` and registerinp;` with` the `connmuiC21-ting bore or channel ofthe tube fThe said cap 38 ,tits` the bore in said valve, permittingthevalve` to move vup `and down thereover. T-hepipe, 7 and its cap 8 Ahave the two openings `10"and 11, in one side, which are adapted .to effect communication alternatelybetween f,the inside of said'pipe and the transverse,.openM ings 1.2 andlin .said valve. `Said valve iS" throughthe pipe 24 to the chamberl, iilling the.latter,.the cup 2 s iilled and drops, aided by its weight, and opens an annular passage -.between'the lower end of the tube 6 andthe exhaust-channel 9, and porty 16. Steam passes from the pipe 7 throughfthe ports 12, 10 and pipe 14:'to the left-hand end of the cylinder 26V to push the piston 27 to the right, causing ythe rod 28 to roclr the pitman 31 to cause therod 35 to shut oi water from the-boiler.. When the water in the boiler falls below the level of the pipe 24, steam Vwill Lpass from the' boiler through the pipe 24 into the chamber 1. rThe entering'steam will blow out most of the water from within the ioat 2 through the small chamber 37 and pipe22, but enough will remain in the chamber 1 to buoy up said float, whichk in rising, will close the port 12-10 to the pipe 14E, and open the port 11-13 to the other pipe 15, so that steam will enter the right-hand side of the cylinder 26 to shift Vthe piston27 to the left, causing it to. act upon the injector toadmit water to the boiler. Since the distance ,from the pipe 24 to the top of the'` loat 2 is so small, theoperation of the def vice in restablishingthe water-level in the boiler is very quick and automatic, and so allows but a small amount of water to escape by way of the pipe 22 each time. rllhe :figure shows the positions of the parts of the device at this time.

It will be seen that the action of my Aimproved devices is, therefore, entirely automatic, and governed by the water and steam pressure in the boiler, to actuate upon said intermediate mechanism to cause the injector to alternately 'supply water to, or to cut of communication with the boiler.

Having described ymy invention, Vwhat 1 claim as new, and desire4 to secure by Letters Patent, is:

1. A device for regulating the water-level in boilers, comprising a cylinder containing a piston whose rod extends externally thereof, an arm to which said piston is pivotally connected intermediate its ends, connectingrods fromlthe ends of said arm to the steam and water admission valves of an injector, a closed vessel having a diminished basal portion, the latter provided with spaced exit-ports and an exhaust-port out of line therewith, a valve movable in said diminished'end past said portsjand having a cenl tral longitudinal hollow closed at the lower end, and alsoV having orifices adapted to y i i v eifectoccasional communication between the said hollow and said exit-ports alternately, communications between said exit-ports respectively, and opposite ends of said cyl- Copiesof this patent may be obtained for inder, a float in said vessel connected to said valve, said vessel having a valve-controlled communication with a boiler, and

Va conduit in communication Y between the steam-dome o f the boiler and the hollow of Said valve, said float when moved down by water entering from the boiler being-adapted to move the valve to shift the steam from one of saidexit-ports to the other, and when causedrto rise'by steam entering the vessel from the boiler, to reestablish communica-V tion between the hollow of the valve and the other exit-port. v

2. A device for rregulating the'water-level in boilers, comprising a cylinderr containing a piston whose rod extends externally thereof, an arm to which said piston is pivotally connected intermediate its ends, connectingrods from the ends of said arm to the steam and water admission-valves of an injector,
